Hi,
wouldn't this loop fail to end when x >= 0x80000000?
Sure, such value probably cannot occur where this is currently used,
but it seems like a landmine for the next developer to step on.
Indeed, thanks. I've sent the patches for consideration which avoid
function duplication and potentially infinite loop.
